[0029] See also Figure 1-Figure 7 The present invention provides a technical solution: a toothbrush for automatically squeezing toothpaste, comprising a toothbrush body assembly 100, a toothpaste box assembly 200 and a toothbrush head assembly 300; the toothbrush body assembly 100 and the toothpaste box assembly 200 cooperate with each other, and the toothbrush head assembly 300 is connected to the output end of the toothpaste box assembly 100;
[0030] The toothbrush body assembly 100 includes a toothbrush rod 101, a first toothbrush end cap 102, a support frame 104, a circuit board 105, a battery 106, a motor 107, and an output shaft 108. The toothbrush rod 101 is through-through, the first toothbrush end cap 102 is detachably fixed to both ends of the toothbrush rod 101, the circuit board 105 and the battery 106 are both fixed to the support frame 104, the motor 107 is fixed to the first toothbrush end cap 102, the output shaft 108 is provided at the output end of the motor 107, and the output shaft 108 is provided with a first connector 1081. The support frame 104 is fixed in the toothbrush rod 101, and the toothbrush rod 101 is provided with a switch button. The switch button, circuit board 105, battery 106, and motor 107 are electrically connected.
[0031] The toothpaste box assembly 200 includes a toothpaste box body 210, a toothpaste box end cap 220, a toothpaste pushing piston 230, a toothpaste pushing blade 240, a screw 250 and a toothpaste outlet end cap 260. The toothpaste outlet end cap 260 is provided with a second toothpaste outlet 261. The toothpaste outlet end cap 260 is fixed to the toothpaste box body 210 and is detachably connected to the toothpaste rod 101. The toothpaste box body 210 is through-through, one end of the toothpaste box body 210 is sealed by the toothpaste box end cap 220, and the other end is provided with a first toothpaste outlet 211. One end of the screw 250 passes through the toothpaste box. The end cap 220 has its other end near the first toothpaste outlet 211. The screw 250 is located inside the toothpaste box body 210 and is screwedly connected to the toothpaste pushing piston 230. The toothpaste pushing blade 240 is fixedly arranged on the screw 250 at one end near the first toothpaste outlet 211. The toothpaste box body 210 is provided with a first slide rail 212. The toothpaste pushing piston 230 is provided with a first slide groove 231. The first slide rail 212 and the first slide groove 231 are slidably engaged. The end of the screw 250 extending out of the toothpaste box end cap 220 is provided with a second joint 251, and the second joint 251 is connected to the first joint 1081.
[0032] The toothbrush head assembly 300 includes a toothbrush head 310, and a hole 311 connected to the toothbrush bristle interface 312 is opened at one end of the toothbrush head 310. A toothpaste delivery tube 320 is provided in the hole 311. One end of the toothpaste delivery tube 320 passes through the second toothpaste outlet 261 and is connected to the first toothpaste outlet 211. The toothbrush head 310 is plugged and fixed to the toothpaste outlet end cover 260.
[0033] The working principle of the present invention is as follows: when the switch button is pressed, the motor 107 starts to work, which drives the output shaft 108 to rotate. The rotation of the output shaft 108 drives the screw 250 connected thereto to rotate. The rotation of the screw 250 drives the toothpaste pushing piston 230 to squeeze the toothpaste disposed in the toothpaste box body 210 forward. In order to increase the pushing force, a toothpaste pushing blade 240 is provided on the screw 250 at the toothpaste outlet. The toothpaste pushing blade 240 squeezes the toothpaste from the first outlet 211, enters the toothpaste delivery pipe 320, and then passes through the hole 311 to the toothbrush bristles. After the toothpaste is used up, the toothpaste box assembly 200 can be directly replaced. The toothpaste outlet end cap 260 of the toothpaste box assembly 200 is disassembled from the toothpaste rod 101 on one side and the toothpaste outlet end cap 260 is unplugged from the toothbrush head 310 on the other side to remove the used toothpaste box assembly 200. The reverse operation can be performed to install a new toothpaste box assembly 200. Of course, the toothbrush head assembly 300 can also be replaced after being used for a period of time.
[0034] Further improvements of the present invention: a limiting protrusion 1011 is provided in the toothpaste rod body 101, and a receiving block 109 for receiving the motor 107 is fixedly provided on the support frame 104. The receiving block 109 is provided with a through hole 1091, and the output shaft 108 passes through the through hole 1091. The two ends of the receiving block 109 of the support frame 104 are respectively limited by the limiting protrusion 1011 and the first end cover 102 of the toothpaste.
[0035] Further improvement of the present invention: a magnetic charging head 1021 is provided on the first end cap 102 of the toothpaste, and the magnetic charging head 1021 is electrically connected to the battery 106. The magnetic charging head 1021 is used to connect to an external power source to charge the battery 106.
[0036] A further improvement of the present invention is that the first joint 1081 is a first tooth, the second joint 251 is a second tooth, and the first tooth and the second tooth are plugged into each other. To ensure accurate alignment of the first tooth and the second tooth, a slide rail can be provided inside the toothpaste rod 101, and a slide groove can be provided on the outside of the toothpaste box body 210, so that the slide rail and the slide groove can slide together.
[0037] Further improvements of the present invention: The toothbrush head assembly 300 further includes a spring 330 and a plug 340. The spring 330, the plug 340, and the toothpaste delivery tube 320 are sequentially arranged in the hole 311 from the inside to the outside. When the electric toothbrush squeezes the toothpaste, the plug 340 and the spring 330 contract and the plug 340 opens, allowing the toothpaste to be squeezed from the hole 311 into the position of the toothbrush bristles. When the electric toothbrush is not squeezing the toothpaste, the spring returns to its original position and the plug blocks the toothpaste outlet, thereby sealing the toothpaste inside the electric toothbrush and preventing the water used in brushing from contaminating the toothpaste in the tube.
